Works fine for me! And I imagine a lot of people, as I haven't read about this before. Are your projects saved on some sort of network share or Dropbox or flash drive or etc. etc.? I assume you don't habitually rename them randomly for fun.

Did you try to uninstall Internet Explorer? The start page is rendered with HTML and an IE view because it's the only browser guaranteed to be installed with Windows. If you have some kind of IE customisations it could break the start page.

@Saint Mikke @Ashley @Tom,I have tried to uninstall internet explorer, but it does not work either.I have also tried to change internet security options with the same result... I do not know what to do, I have installed C2 in my new computer that runs windows7, and I have not changed anything...
